“Changing the diamond to a black diamond, FYI. Sorry for the jpg… They’ll finish the actual ring soon I hope,” he wrote on the image that accompanied his Tweet.

Deadmau5's Twitter proposal and Kat Von D's response

The Hollywood tattoo artist responded five minutes later, Tweeting, “Yes!” which was followed by a very long row of exclamation marks.

The proposal, while hardly conventional, is fitting given so much of the couple’s relationship, including break-ups – and make-ups – has been freely shared with their millions of followers.

Just last month, on November 10, the couple made it clear via their respective Twitter accounts that all was not well. A stream of cryptic Tweets indicated the couple were having problems, before Kat too things into her own hands, Tweeting plainly: Clarification: Deadmau5 and I are no longer together.

The couple made up quickly, filling their Twitter profiles with friendly messages and images of them together.
